Bowman Permanent Magnet Motor Replication 2008

[eavogels]

Did he never re-build another Bowman and show a video? I find this very surprising.

He sure tried; we all did. With no success. This is not new: every now and then someone makes something that works. But (of course when it is not a hoax) even the inventor is not able to replicate. The problem is that no one knows why it worked in the first place. A very small miss alignment (or a magnet glued with flexibel glue) can be the reason that a device finds it imbalance. Replications often are build with other small miss-allignments and therefore they don't work.

One more very important thing with the Bowman: all magnets should have the same strength, otherwise the magnetic gears are not stable. If you have 16 magnets and put them on a gauss meter, you'll see that only 3 or 4 are the same.

Sean I commend your effort. And it look good.

I sure I don't just talk for myself when I say good luck on your work and we are looking forward to you getting back to talk on the forum as well as building.

PS I sent you another email with a video of a magnet being accelerated, by field manipulation.

Hi Alan

Just replied to your email, sorry for delay, but work overload getting in the way again of playing with magnets grrrrrrrrrr

I got the Alnico magnets arrive last weekend and will try and find time to Mill out the Rotors this weekend to fit them.
Also nice shiny Brass nuts arrived so I can get rid of any Steel that would influence the field as such.

Cheers

Sean.

I have been searching for a good Small Desktop CNC machine however, is there one that is affordable?

Thank-you
